Abstract
A method of setting a setpoint operating state of a hybrid drive of a vehicle, where the hybrid drive includes as drive motors an internal combustion engine and at least one electric motor, and the output shafts of the drive motors are mechanically linkable to a drive train of the vehicle. Depending on the instantaneous power demand on the drive motors of the hybrid drive and the instantaneous power capacity of the drive motors of the hybrid drive, an optimal crankshaft speed of the combustion engine may be determined, and this crankshaft speed may be set by coordinated actuation of the drive motors of the hybrid drive, while maintaining the instantaneous power demands.
